Product Manual
Introduction
Step up a 12 VDC battery to between 13.5 and 17.0 or 24.0 and 27.5 VDC in 0.5 VDC increments (via 3
position DIP switch), or stabilize a 12 or 24 VDC power system. Safety features include reverse input
protection, low input voltage alarm, low output voltage alarm, over temperature shutdown and alarm,
and output overvoltage crowbar. If the input voltage exceeds the regulated output voltage, the unit
simply passes the voltage through with full LC ltering and a single schottky diode drop (0.5 VDC or less).
Optional features include a dry contact alarm relay output, and remote panel monitoring with On/Off
control.
Applications include temporarily brightening 12 volt headlights or work lights, increasing voltage into
an automotive or marine ignition system for hotter spark and/or prevention of failures due to voltage
drop during engine start, stabilizing 12 and 24 VDC power systems in marine, automotive or aeronautical
environments and more.
